Answer:
It is the last choice, 53.33%.
Step-by-step explanation:
The number who don't watch NBC is 20+4 = 24.
So the fraction who do not watch NBC = 24/45
= 53.33%
Answer:
Two positive zeros, no negative zeros, two complex roots.
Step-by-step explanation:
The given function is 
According to the fundamental theorem of algebra, the function will have 4 roots.
The graph of the function intersects the positive axis at two points.
Hence the function has two positive zeros and no negative zeros.
The two remaining roots are imaginary. The function has two complex zeros.

Step-1 : Multiply the coefficient of the first term by the constant 6 • -10 = -60
Step-2 : Find two factors of -60 whose sum equals the coefficient of the middle term, which is -11 .
-60 + 1 = -59
-30 + 2 = -28
-20 + 3 = -17
-15 + 4 = -11 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 4
6n2 - 15n + 4n - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
3n • (2n-5)
Add up the last 2 terms, pulling out common factors :
2 • (2n-5)
Step-5 : Add up the four terms of step 4 :
(3n+2) • (2n-5)
Which is the desired factorization
Final result :
(2n - 5) • (3n + 2)
Models are patterns that are used to predict measurements and populations
<h3>How to model the tree</h3>
The question is incomplete, as the model and the dataset to model that growth of the tree are not given.
So, I will give a general explanation
If the model of the tree follows a linear model (e.g y = 2x + 3), then the model is not reasonable.
This is so because, population and growth cannot be measured by a linear model
However, if the growth of the trees follow an exponential model (e.g y = 2(3)^x), then the model is reasonable

Answer:
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<h3>y=-15x-5 and 11x+y=-17</h3>
First, you have to substitute.
Then, you solve.
Add by 5 from both sides.
-4x-5+5=-17+5
Solve.
-17+5=-12
-4x=-12
Divide by -4 from both sides.
-4x/-4=-12/-4
Solve.
-12/-4=3
<u>x=3</u>
y=-15*3-5
Solve.
PEMDAS stands for:
- Parenthesis
- Exponents
- Multiply
- Divide
- Add
- Subtract
15*3=45
Rewrite the problem down.
y=-45-5
Solve.
<u>y=-50</u>
<u>Therefore, the correct answer is y=-50 and x=3.</u>
